Wanna give Toshiro a run for his money? Try this, as a base.
G: Byakuya
Turn 1- Bankai
Turn 2- Byakuya-Surprised, use Kageyoshi on him, attack, pitch him to get a Renji-Protector or Determined, then, pitch the new Renji for a severely reduced Renji-Unleashed. Use him to get Byakuya-Unstoppable, giving Renji Aggressive, and Rikichi-Admirer to get Renji-Pointing to your hand. Unleashed attacks, boost him, renew smack again, and on Turn 2, you can do upwards of 20 power.
*THIS IS ALL PURELY HYPOTHETICAL, BUT DEVESTATING IF PULLED OFF!*
